This zip file contains 11 different activities which can be used to compose a unit for biology students introducing them to basic concepts about the structure and processes of cell membranes. While these lessons were originally designed to correlate to the performance indicators of the New York State Living Environment/Biology curriculum, the components of this lesson may be easily used in other biology courses as well. Topics such as basic membrane structure, diffusion, osmosis, active transport and applications of these processes are addressed. Specifically the packet contains the following items with all files except the PowerPoint posted in both pdf and word format for easy edit for specific teacher needs.
-- Marzano self assessment scale for students specific to this unit
-- Common Core, NGSS and NY State Living Environment Core Curriculum Correlations
-- Cloze notes handout for students with learning goals
-- 43 frame PowerPoint to accompany the cloze notes which includes two sets of embedded bell ringer questions with answers
-- Membrane Processes worksheet 1 with key (contains 13 multiple choice and written response questions)
-- Membrane Processes worksheet 2 with key (contains 18 multiple choice and written response questions)
- Membrane Processes Practice quiz for students with key
-- Membrane Processes Quiz with key containing 20 questions involving multiple choice and written responses
-- 13 question membrane processes crossword puzzle with key
AND 3 labs relating to these topics as described as follows:
-- The Diffusion Lab introduces the student to the concept of diffusion and is an activity that in various formats has stood the test of time. Students deduce and learn that small molecules like iodine and glucose can pass thorough a semi-permeable membrane while large ones can not. Students will collect data and then answer 17 questions requiring both written responses and multiple choice format answers. The last page of this seven page lab lists possible suppliers for the relatively inexpensive materials required for this lab.
-- The red onion osmosis activity is a simplified version but an earlier and different version of the lab required in the Living Environment course in New York State. This six page lab activity requires students to view red onion epidermal cells in a tap/distilled water and then in a salt water solution. Students will be required to draw their observations and then answer 12 conclusion questions requiring labeled drawings, written responses, as well as multiple choice format answers.
-- The Sucrose Solutions and Osmosis Lab and Common Core Activity allows the teacher to use relatively inexpensive materials to study the process of osmosis in a qualitative and quantitative manner. The introduction to the lab provides reading on concepts pertaining to osmosis, including hypertonic, hypotonic and isotonic solutions with illustrated graphics for visual learners. The lab activity involves using simple materials including sucrose solutions of different concentrations to measure mass changes and determine the identity of an unknown sucrose solution. The students will be required to record and graph the collected data. This is then followed by 10 questions requiring written responses to assess student learning.
This last lab is correlated to the NGSS standards, Common Core literacy and math standards, as well as the performance indicators for the Living Environment core curriculum. Suggested teacher instructions (and time saving/cost cutting suggestions) for this nine page activity are included on the last page of this lab and should not be given to the students.
There are 46 total pages of student materials enclosed alone and over double this when the enclosed answer keys are counted to provide many resources for teaching a unit on membrane processes.

Upon the completion of this unit the student will be able to:
1. explain how cells, tissues, organs and organ systems work together to achieve function in multicellular organisms.
2. define the following terms associated with processes of the plasma membrane; diffusion, concentration gradient, osmosis, solute, solvent, permeability and semi permeable.
3. correctly label the following structures in a diagram of the plasma membrane; phospholipid bilayer, transport proteins, and receptors.
4. list three functions of the plasma membrane.
5. given diffusion and osmotic situations, correctly indicate the direction of osmotic flow and explain why this is so.
6. list two differences between passive transport and active transport.
7. explain the difference between pinocytosis and phagocytosis.
8. follow directions to use and interpret common chemical indicators such as Lugol's solution and glucose indicators.
9. design a model of a cell and relate this model to the size of diffusing molecules.
10. explain changes associated with the cytoplasm of a plant cell in distilled and saline solutions
Common Core Standards Addressed
RST.9-10.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks, attending to special cases or exceptions defined in the text.
A-CED.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
MS-LS1-2. Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
Performance Indicators NY State Living Environment Core Curriculum
1.2g Each cell is covered by a membrane that performs a number of important functions for the cell. These include: separation from its outside environment, controlling which molecules enter and leave the cell, and recognition of chemical signals. The processes of diffusion and active transport are important in the movement of materials in and out of cells.
